SHUTTLE-BOX FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 594,704, dated November 30, 1897.

Application filed Ju e 18, 1397.

- senting like parts.

This invention has for its object the production of improved means for stopping the shuttle in the shuttle-box, so that the shuttle will be more centrally held and cushioned to prevent shock as it is brought to rest, a bridge or guard for the picker being also provided to prevent the latter from rising or jumping when starting.

By means of my invention a definite position for the shuttle in the shuttle-box is insured, which is of importance, particularly in looms provided with automatic filling-supply ing mechanism, though my invention is not restricted in its application to such looms.

Figure 1 is a top or plan view of a portion of a lay with its shuttle-box and a shuttle therein to illustrate my invention; and Fig. 2 is a perspective view of the casting detached, which provides supports for the shuttle-stops, the picker-bridge forming a part thereof.

The lay A, slotted longitudinally at a for the picker-stick and having at its end a shuttle-box comprising a back piece a and front guide I), and the picker P are and may be of usual construction a shuttle S being shown at rest in the shuttle-box.

At the outer end of the shuttle-box I have secured to the loom a casting comprising a two-part base d, connected at the outer end by a raised bridge or guard 61, crossing the longitudinal passage d extended through the base-plate and in'which the picker-stick swings. Each part of the base is shown as upturned at its inner end to form outwardlydivergent supports or abutments d symmetrically located relative to the longitudinal central line of the shuttle-box. These abutments are located at the outer end of the shuttle-box, as shown in Fig. 1, on opposite sides of the entrance to the passage d Serial No. 641,268. (No model.)

in the base 01 of the casting. The stops 0r abutments are in use provided with suitable leather or other cushions 0, held in place by suitable bolts or screws 5, Fig. 1, the abutments having bolt-receiving holes 3. Suitable bolts 6 secure the base cl to the lay. The inclined inner surfaces of the cushions 0 conform substantially to the inclination of the shuttle just back of its point 5, so that as the shuttle arrives fully in the box its inclined 6o sides will meet the inclined faces of the cushions, taking up shock and centering the shuttle in the box. The picker plays freely beneath the guard cl, but any tendency of the picker to lift or jump in starting is prevented 65 by the guard. When used with the Northrop type of loom, this guard will also prevent the picker from engaging any threads on the hopper that may be slack enough to get in the way.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The lay, slotted to receive the picker, the picker, and a guard located on the lay above the starting-point of and independent of the picker, to prevent the latter from lifting at the beginning of its inward stroke, substantially as described.

2. The lay having a shuttle-box, the picker, a guard therefor and independent of the latter to prevent it from lifting at the beginning of its inward stroke, and outwardly-converging fixed abutments at the outer end of the shuttle-box, to position the shuttle centrally therein, substantially as described.

3. As a new article of manufacture,apickerguard and shuttle-positioning device, comprising a base having a central passage-way, an upturned guard over one end of the latter, .and upturned, divergent abutments on the base at the other end of the passage-way, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES H. NORTHROP.
